[Mgs] MGA Clutch recommendations

[J. F. Juhas]

I have been having considerable difficulty with the clutch(s) in my MGA 
with a lightly modified 1622 engine.  Lots of slipping issues.  Without 
going into the considerable history of what I have done in attempts to 
remedy it, what are you all using in your MGAs?  The choices I know of 
are 1) stock or heavy duty standard MGA clutch & PP; 2) Twin Cam 
pressure plate; 3) MGB pressure plate with some choice of MGA disc; 4) 
uprated MGA pressure plate, as in more clamping force; 5) choices of 
clutch disk material.  I have now tried the stock-type clutch faces, 
kevlar and ceramic.

I have had oiling problems (from the engine rear scroll seal) but my 
engine shop is convinced that the amount of oil that I have shown him 
would not be enough to make a conventional clutch slip.

So, what combinations have you all found work for you?  I recognize that 
I may have some other issue somewhere but I hope this advice might help 
me to eliminate the materials as a variable.
